SPECIFICATION forming part of Letters Patent No. 326,072, dated September 8, 1885. I

Application filed November 3, 1884. (No model.)

.70 Ml whom it may concern:

Be it known that I, ALLEXEY WV. VoN SCHMIDT, of the-city and county of San Francisco. State of California, have invented a new and Improved Movable Joint for Discharge- Pipes for Dredge-Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,.and to the letters of reference marked thereon.

My invention relates to certain new and useful improvements in discharge-pipes for dredging material.

It has for its object to so construct the discharge-pipe that when connected with any suitable scow or float and connected with other pipe that the dischargepipe' will adjust itself to any required angle; and my invention further consists in the details of construction necessary in the apparatus, as will be hereinafter more fully set forth.

In order that those skilled in the art to which myinvention appertains may knowhow to make and use my improved movable joint, I will proceed to describe the construction and operation of the same, referring by letter to the accompanying drawings, and in which I have, for sake of convenience, shown only a portion of a side section of a scow-boat, dredge, or float, as it will be clear to any one skilled how to arrange the pipe for work.

Figure l is a side elevation representing a vertical section of my improved movable elbow-joint and necessary adjuncts as attached to side of scow or float. Fig. 2 represents in end view the movable elbow-joint and bearing for step of same. Fig. 3 represents in top view the clampstrap to hold top of movable elbow-joint. Fig. at represents same in front view. Fig. 5.1'epresents in top View the box for step. Fig. 6 represents flange and journal on which the movable elbow-joint swings. Fig. 7 represents top view of the movable elbow-joint and portion of dredge boat or float.

Similar letters of reference denotelikc parts in the several views.

A represents the dischargepipe coming from dredge. B represents the first elbow. 0

represents a section of pipe, the lower end of p which works in a gland, a, well packed and fitting into the upper end of the movable 1 elbow D. The upper end ofthe movable elbow-joint is made with a bell-shaped end the after part of which is firmly secured to the side of dredge or boat. This clamp is made in two halves, as shown in-Fig. 3, with screw-bolts to secure the two halves around the upper part of the bell of the movable elbow-joint I). The lower part of the movable elbow-joint has a gudgeon or iron pin, 0, on which the elbow-joint turns. This iron pin or gudgeon is placed in line with the center of the elbow-pipe, and secured to plate or bracket (I, cast on the lower part of elbowjoint D. The iron pin or gudgeon runs ina box. e,secured by screw-bolts to timbers f, which timbers are secured by iron bolts -g to side of dredge.

.I do not of course wish to limit myself to all of the exact details of construction shown,

as they may be varied in many particulars without departing from the spirit of my invention, the object of my invention being to direct the movable joint in any direction,

whether the discharge-pipes are required to lead forward, sidewise, or backward; The movable elbow-joint will conform to any angle required, by reason of its resting on a central point or pivot and being secured by a bandstrap at the upper end of elbow-joint.

What I claim as new, and desire to secure by Letters Patent, is

The clamp-strap b, in combination with movable elbowjoint D, and iron pin or godgeon c, and packi'nggland a, elbow-pipe B, and straight pipe 0, with bracket-bearing d, substantially as and for the purpose set forth.
